Function

By actuating the recirculation switch (N22s2) on the AAC [KLA] control and operating unit (N22) (except code (581) Comfort automatic air conditioning) or the air recirculation switch (N22/7s2) on the comfort AAC control and operating unit (N22/7) (with code (581) Comfort automatic air conditioning), the panoramic sliding roof can be closed. The last approached position of the panoramic sliding roof is stored in the process. When the recirculated air mode is completed the sliding roof or power windows move back to this stored position. Although this only happens if the panoramic sliding roof has not been operated manually during recirculated air mode.

If an opening operation is started via the air recirculation switch while closing, the panoramic sliding roof reverses directions
